Bosz, 53, led Ajax to the Europa League final in his only season in charge of the Netherlands club. It was their first European final in 21 years, but he has now signed a two-year deal to replace Tuchel at the helm of the Bundesliga second runners-up.

He was previously under contract with Ajax until 2019. Dortmund have accordingly agreed to provide a compensation package to secure his services.

Ajax confirmed on their official website that an agreement had been reached with Dortmund.

Their general manager, Edwin van der Sar, who also happened to play for Manchester United, described it as a “good deal”. “I have mixed feelings about this move. When we brought Peter to Ajax last summer it was not the intention that the partnership would end after one year.”

“(But) we have had a great season, especially in the Europa League. As with our players, the coach also attracts the attention of clubs from Europe’s top leagues.”

“We have had a great season, especially in the Europa League. As with our players, the coach also attracts the attention of clubs from Europe’s top leagues.”

“These talks convinced me that this ought to be the next step for me,” Bosz said at a press conference on Tuesday, revealing he had spoken with Dortmund chief executive Hans-Joachim Watzke and the club’s sporting director Michael Zorc for around three hours. “I got a good feeling. It was a respectful discussion. I am convinced that we can work very well together.”

“We had a very, very good feeling about Bosz from the outset, the feeling that something can really grow together here,” Watzke added.
